Two brothers from Somerset plan to retrace their great-grandfather's steps by exploring Patagonia in a Victorian manner - including wearing traditional costumes.

Julian and Oliver Campbell, from Norton-sub-Hamdon, are setting out on Thursday for a two-month trek through the South American wilderness.

The inspiration behind the trip comes from great-grandfather W.O. Campbell, who published a book called Through Patagonia in 1901, detailing his many exploits.

They will use only Victorian-style instruments and equipment - ignoring the chance to use high-tech satellite guidance and modern clothing.

Great-grandfather Campbell was the inspiration for the trip

Oliver Campbell, 27, told BBC News Online: "We want to get back to the original way, with not much between us and the environment.

"We also want to see if we are as tough as our great-grandfather - but we won't kill ourselves doing it."

The aim is to head from Buenos Aires on a scenic route to Mount Fitsroy, with the help of a guide where necessary.

The brothers will keep a video documentary of their adventures.
